metamer: Create Data with Identical Statistics

Description

Creates data with identical statistics (metamers) using an iterative algorithm proposed by Matejka & Fitzmaurice (2017) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1145/3025453.3025912")}.

Overview

Create metamers with the metamerize() function.

Some helper functions included:

• draw_data() for drawing 2D datasets by hand and densify() for increasing the point density of those drawings.

• delayed_with() for defining statistics to preserve.

• moments_n() for preserving moments of order n.

• mean_dist_to() for minimizing the mean distance to a known target dataset.

The as.data.frame()/⁠[data.table::as.data.table()] methods included will turn a ⁠metamer_list' into a tidy data.frame.

Inspired by Matejka & Fitzmaurice (2017) awesome paper.
